I, too, have been atomically dissecting that meme to find the racism, and you know I won’t rule out that when the GOP makes a joke about that actually is what they mean, but it appears to be a thing fans of Harris also meme about.
She was telling a folksy story of growing up and she recounted how her mother had asked if the kids had just fallen out of a coconut tree. It’s a cute alternative to “were you born yesterday” or something like that.
I dunno, it has big “what doesn’t everyone say ‘porch monkeys?’” energy.
